Windows desktop client ~10x times slower than web frontend?

Nextcloud version: 25.0.3
Operating system and version: Ubuntu 22.04 LTS
Apache or nginx version: Apache/2.4.52 (Ubuntu)
PHP version: 8.2

The issue you are facing:

Via the web frontend I get the follwonig speeds:

  • download ~ 2,4 GBit/s (O.K. as expected)
  • upload ~ 1,2 GBit/s (why only 1/2 of download)

Via the nextcloud app (Ver.: 3.6.6) on windows 10 I get the follwoing speeds:

  • download ~ 0,15 GBit/s (ugh, at least 10x times slower)
  • upload ~ 0,1 GBit/s (ugh, at least 10x times slower, also upload slower then download)

My questions here are:

  • 1. Is the slower speed of the windows app as expected due to the nature of the app? (webdav)

    1. Why do I only get half the upload speed of the Download speed?
      (Server/Client - CPU: both i9 Intel 10gen, both NVME SSD’s gen4)

Is this the first time you’ve seen this error? : Yes

Steps to replicate it:

I’ve just installed a new Nextcloud instance (Ver.: 25.0.3) in my local 2,5GBit/s network.
Server and client are in the same network and are using local hostnames.
I followed the

Hi @Tux_1024,
You are missing the required support template. Please fill this form out and edit into your post.

This will give technical info and logs needed to help you! Thanks.

Problem solving connection speeds would require using tools like smoke ping on your network and detailing your network interfaces, etc. Check nc against whatever else is happening or scheduled on your Lan. Might be something on the windows machine eating up resources, but I don’t know. Good luck and hope you find a nice network monitoring tool (glances or similar) to resolve it.

I’ve updated my original post.
Thanks for showing me the Template.
